How much can the average 40 year old woman bench press?
The average 40 year old woman should be able to bench press 52% of her body weight.
It depends on the average male. Some can bench-press more weight than others, depending on their pectoral, biceps and back-muscle strength they have. Some can bench-press as much as 300 lbs; others may only be able to bench-press only around 100 lbs. Just like there are many different body types of each man, there are different levels of strength that each and every individual 21 y.o. man has.
